v3 Geode cs5536 UART2 wrongly configured

Reported by: edwin_beasant@… Owned by: somebody
Priority: major Milestone: Going mainstream
Component: coreboot Keywords: serial com2 geode cs5536

Patch Status: patch needs review

Description

The UART2 on the AMD cs5536 is incorrectly configured in two places in v3 code and also in v2.
GPIO lines 4 and 3 are swapped and also incorrectly put in IR mode receive (compound fault).
This patch corrects the v3 late configuration and the v3 and v2 early (stage1/cache as ram) mis-configuration of UART2 to addres 0x3f8 not the standard 0x2f8 for COM2.
